INTRODUCTION
S6B0708 is a single-chip LCD driver IC for liquid crystal dot-matrix graphic display systems. It incorporates 192
driver circuit for 64 common and 128 segment and 64 x 128-bit bit-map RAM. It is capable of interfacing with the
microprocessor, accepting 8-bit parallel display data directly from it, and storing data in an one chip display data
RAM. And it generates internal signals for using LCD driving independent of microprocessor clock.
FEATURES
